yes!!!!!!!, please
Re: Adding Normals in OBJ exports
Out of curiosity (because I was looking at this for AMF export - https://freecadweb.org/tracker/view.php?id=608 ), what is the advantage in exporting the normals per-face in OBJ format?
Re: Adding Normals in OBJ exports
For me, when export cad parts to blender if the faces export the normal from surface avoid shading artifacts.
In this image: top with normal's calculate from blender, bottom with normal's included from cad.
Basically the will let you see your objects in blender and others as you can see in your cad software, i mean, nor faceted or shading artifacts.
Cheers.

Re: Adding Normals in OBJ exports
toribio - is that car something you drew in FreeCAD?
The reason I'm asking, is that the normals this patch exports are per-facet, so they probably won't result in smoother shading. I think this patch is producing files that contain the same normals as what would be calculated by Blender, for example. -Ian-

Re: Adding Normals in OBJ exports
Hi, the car is an example of blender wiki, I don't know the internals for polygonal shading, lower image is as seen in the cad app and this is the data needed in blender, and any other app like blender. To add this kind of feature will bring a lot of users from the cad world, the most suitable app for this kind of work in this moment is http://moi3d.com/, but lack of 64 bits version, so big models are pretty impossible to export.
Cheers.
